The answer and the form of the fulfilment of this wish came as an hallucination. She had a vision of Christ’s Sacred Heart “‘surrounded with rays more brilliant than the sun, and transparent like a crystal. The wound which he received on the cross visibly appeared upon it. There was a crown of thorns roundabout this divine Heart, and a cross above it.’ At the same time Christ’s voice told her that, unable longer to contain the flames of his love for mankind, he had chosen her by a miracle to spread the knowledge of them. He thereupon took out her mortal heart, placed it inside of his own and inflamed it, and then replaced it in her breast, adding: ‘Hitherto thou hast taken the name of my slave, hereafter thou shalt be called the well-beloved disciple of my Sacred Heart.’”[120] There is scarcely room to doubt, on the strength of the evidence as presented, that the antecedent longings of Margaret impelled by the conative force of their emotions were the causal factor of this vision. These longings, organized in the unconscious, must have gone through subconscious incubation (as William James has pointed out) and then emerged after maturity into consciousness as a symbolic visualization accompanied by hallucinatory words which were the expression of explicit subconscious imagination. Indeed, all such hallucinatory symbolisms—like the mental phenomena in general of sudden religious conversion—can only be psychologically explained as the emergence into consciousness of subconscious processes. The problem in each case is the determination of the content of the process.[121]
